First time post here.
I have a 2012 Dodge durango Citadel with the 5.7L Hemi has 72,000 miles I am 2nd owner.

Seems lately that the transmission shifts weird. I bought the car used 3 months ago. It doesn't feel like it has the power that it should. Sometimes I push the gas pedal and it is very sluggish. I have read about resetting Control modules or throttle body computer modules on other sites but can't find them now. Any ideas?

 

Resetting is accomplished by disconnecting the battery for 15-20 minutes. Check the maintenance schedule for any recommended maintenance that should be or have been performed by now.
